Cascaded low - density erasure codes are based on sparse random bipartite graphs. very efficient linear time encoding and erasure recover algorithms with the arbitrarily near erasure channel capacity performance of the codes with respect to the algorithms have made them one of the most optimal coding techniques up to now
基於稀疏隨機二部圖的級聯型低密度糾刪碼因其線性時間的編譯碼演算法和可任意逼近刪除通道容量限而成為目前最佳編碼技術之一。Turbo code, which utilizes the condition of random coding and decoding of shannon noisy channel coding theorem, has obtained the performance near to shannon theoretic limit. the performance of turbo code is the best one in all presented coding methods
Turbo碼由於很好地應用了shannon有噪通道編碼定理中的隨機性編譯碼條件而獲得了接近shannon理論極限的譯碼性能。4 lee c y, lu e h, lee j y. bit - parallel systolic multipliers for gf fields defined by all - one and equally - spaced polynomials. ieee trans. computers, 2001, 50 : 385 - 393
近些年來,有限場數值運算被廣泛應用在編碼理論計算機密碼數字訊號處理,邏輯設計,和隨機數產生器等領域上,受到相當大注意。Turbo codes were presented by c. berrou in international conference on communications in 1993. they hang convolutional code and random interleaver together to realize the idea of random coding, and adopt soft input / soft output ( siso ) iterated decoding to approach maximum likelihood decoding ( mld ). turbo codes come closer to approaching shannon ' s limit
Turbo碼,由c . berrou等在icc 』 93會議上提出,它巧妙地將卷積碼和隨機交織器結合在一起,實現了隨機編碼的思想,同時,採用軟輸入軟輸出迭代譯碼來逼近最大似然譯碼,具有近shannon限的性能。Such code is also called gradually good code or shannon code. in 1993, c. berro etc. firstly proposed a new channel code method - turbo code, which employed recursive systematic code 、 the random interleaver 、 map ( maximum a posteriori ) algorithm and iterative decoding algorithm obtained the capacity that had only 0. 7db difference compared to the shannon limitation
1993年c . berro等首先提出了一種全新的通道編碼方式? turbo碼,採用遞歸系統碼與隨機交織器構造turbo碼,並將map ( maximumaposteriori )演算法和迭代演算法應用於解碼過程,獲得了與香農理論極限僅差0 . 7db的性能。The major tasks include : ( 1 ) expand the schema theorem for ga. the schema theorem with binary coding advanced by professor holland is expanded to limited integer, letter, floating point numbers the number of which value is limited, and their hybrid coding.
